X440-G2-24p Fan Speeds

D
What is the go with the X440-G2 fan speeds. We have some of these switches in class rooms and cabinets in classrooms and they are so noisy. We also have some in one of our data centers and its at a much much lower temp, but the same fan speed?

Office Switch:
Events 2.14 # sh temp
Field Replaceable Units Temp (C) Status Min Normal Max
--------------------------------------------------------------------------------
Switch : X440G2-24p-10G4 90.20 Normal 0 10-100 110
Events 2.15 # sh fan

Slot-1 FanTray information:
State: Operational
NumFan: 4
Fan-1: Operational at 7440 RPM
Fan-2: Operational at 7560 RPM
Fan-3: Operational at 7620 RPM
Fan-4: Operational at 7680 RPM

Data Center Switch:
Server Room Edge.1 # sh temp
Field Replaceable Units Temp (C) Status Min Normal Max
---------------------------------------------------------------------------
Switch : X440G2-48p-10G4 52.50 Normal 0 10-100 110
Server Room Edge.2 # sh fan

FanTray information:
State: Operational
NumFan: 4
Fan-1: Operational at 7680 RPM
Fan-2: Operational at 7680 RPM
Fan-3: Operational at 7620 RPM
Fan-4: Operational at 7620 RPM
Server Room Edge.3 #

They're about 40 degrees apart but running the same fan speeds? I have read that <30 and they run half speed? Do they not ramp up on scale with the temperature?

Dear all,

Extreme found a problem with X440-G2 - fans running too high.

https://gtacknowledge.extremenetworks.com/articles/Solution/Fan-Speed

After showing samples of a x440-g2 stack with slot1 having 3 poe devices and slot 2 with no poe devices they gave my ticket to engineering. They found the problem and will resolve it in EXOS 22.7.1-Patch1 which is scoped for mid of October (CR xos0075492)

I am glad they found it. We have ~100 x440g2 switches.

I had a ticket open at GTAC about the same issue.
Their response was that the temparature/fan level is normal

the fan could go as low as 500rpm, but i never seen it like this!
the temparature shown is an addition of ambient + cpu

Seems silly that the only settings for these fans seem to be Off, Noisy or Screaming...

The X440G2 does not have "setting" for the speed = you can not set the speed.
The X440G2 does have linear fan speed = there is 255 speed levels. It should not be "off, noisy, screaming".

There were bugs in the firmware regarding the fan speed control = I suggest to check your firmware.

The fan speed depends on the PoE consumption and ambient temperature.

I was told the temperature value is an addition of cpu temp + ambient temp
So in my eyes it is impossible to reach a normal value af 10 degrees celsius

the x440g2 is very noisy, we installed them instead of A2 and A4 switches. these were not that loud.

I run into the same problem. With 2 connected PoE Devices the fanspeed increase up to 10.000rpm. After disabling the PoE Devices, the fanspeed went down to 2.100rpm.
In my opinion, these switches are to noisy for any office enviroments and useless with PoE.

I can confirm that version 30.3.1.6 solves the problem with with fans running too high when less than 6 poe devices are connected (CR xos0075492)
The fans are now 2000rpm instead of 6000rpm

summitX-22.7.1.2-patch1-8.xos also solves the problem

I have tried multiple releases (including the ones above), including the latest firmware as of this post - EXOS 31.1.1.3.  Even with 0 PoE ports enabled, I am above 6k consistently with almost no active devices on the switches (pair of X440G2-48p-10G4 stacked).  7680RPM or so seems the average for all the fans.  3 3935i PoE APs on each switch (evenly balanced - total of 6) has no impact on the fan speeds versus the scenario with all of those ports turned off on the switch, delivering 0 power to the APs.

Following these steps to reset fan speeds to defaults doesn't help:

https://extremeportal.force.com/ExtrArticleDetail?an=000058778&q=x440-g2 fan speed

I can lower speeds with the other debug command it shows but I don't know what would be safe to use.  Too bad a manual debug command with a static value is needed...versus automatic practical lower RPM values when under low load...
